The Royal Observatory Greenwich, founded in 1675 by King Charles II, has been haunted for centuries by the ghost of its first Astronomer Royal, John Flamsteed. Staff and visitors report seeing a figure in 17th-century dress moving through Flamsteed House and the observatory buildings, examining astronomical instruments and appearing to make observations. Witnesses describe this apparition as deeply absorbed in his work, maintaining the same dedication to celestial study that defined Flamsteed’s earthly life.

The Octagon Room, designed by Christopher Wren as the original observation space, experiences the most frequent paranormal activity. Security guards working night shifts report hearing the scratch of quill on parchment, the whispered calculations of mathematical work, and footsteps pacing the room as if deep in thought. Some witnesses describe seeing candles mysteriously lit in the historic space, providing illumination for ghostly astronomical observations. The room’s historical telescopes and instruments occasionally appear to have been moved or adjusted overnight, despite being secured and monitored.

Beyond Flamsteed’s ghost, staff report other paranormal phenomena connected to the observatory’s long scientific history. The meridian line courtyard, where the Prime Meridian of the world is marked, generates reports of temporal distortions - visitors experiencing brief moments of seeing the location as it appeared in different historical periods. Conservation staff working with antique astronomical instruments report experiencing vivid mental images of the scientists who used them and occasionally feeling guided by unseen hands when handling particularly significant pieces. The observatory’s role as the birthplace of modern time-keeping seems to have created temporal anomalies where past and present occasionally overlap.
